How is the Guru described in relation to Brahman, and what kind of worship does this lead to?

The text presents the Guru as the ultimate spiritual reality. Chapter 45 states that while Brahman is eternal and the world is transient, the Guru alone is the true Brahman and a 'solid mass of Brahman-consciousness.' Because of this identification, the recommended path is to renounce the transient world to cultivate dispassion (Vairagya) and to meditate exclusively on the Guru. This practice, where divinity is seen in all beings through the lens of the Guru, ultimately leads to a state described as 'undifferentiated worship' or 'Abheda-bhajan.'
